1: just get an aluminum hood (if you don't already have one) check it with a magnet.

2: what would the hood scoop be use for? not just for looks i hope... if you want a useless scoop to add drag, then just et an aluminul T2 hood.

personnally i'm going CF reverse vented. like the Odula hood after the FMIC conversion. and I will be painting the CF on the outside to match my body. with the black FMIC the car should look pretty subtle.

hope that helps your decision.

Trust me. The only piece of inner skeleton you can cut out weighs all of .8lbs on an AL hood and 1.3lbs on a steelie.

And BTW........your hood will flop around like a wet noodle when you're done with it.

But hey........whatever floats your boat.

Mazda made efforts to save every pound they could (ex. aluminum jack that saved something like 1.3 pounds). I think if this were a good/feasible idea, Mazda would of done it. That support is there for a reason.

Do you say the same thing to folks that replace the stock hood with a random aftermarket FGRP hood?

Don't cut it unless you want it to sag in the middle. You could replace the skeleton with 1 inch pieces of plexiglass (mounted longways for stablility) and adhere them to the main hood... Not really a great idea though unless it's just a back up hood you have laying around because you will probably not like it and want to throw it away afterwords.

Or you could cut the skeleton off and put a really thick piece of some sort of foam between the flat space on the fan shrowd and the hood. Kinda liek a spacer...

Bottom line is unless you have an extra hood laying around, it's a waste of time and a good hood.

FWIW, I've done this to several hoods and the most recent one was a customer's FC hood. It doesn't sag in the middle, but it will flex around quite a bit compared to the stiffness it had before.

I'm not so sure about the vert thing... The last vert I drove didn't have an alum hood. But, lots of 86's had alum hoods. No telling which ones.. bring a magnet.

Don't make a home made hood scoop,,,, you will probably engineer it wrong and the air flow will actually cause terbulance and make the engine run hotter. My suggestion if you have an extra hood...

reverse vent!

cools better....
looks different...
if you make the inner ridges right it will support the hood enough to completely remove the skeleton...

only issue is keeping the moisture out... maybe some mesh and and a catch pan.

make your own out of some extra sheet metal. stick a couple hoses in the bottome ( drill holes) for the water to drain once it collects. It will act sort of like the sunroof and hatch drainage system.
